Unfortunately the good news turned sour.
First I noticed a poorly soldered connection and crooked exhaust. Easy enough to fix, simply replace the right side exhaust assembly.
Then I noticed the LEFT side intake manifold is incorrectly formed, so the intake blocks the oil filler plug from removal from the crankcase. That obviously is unacceptable, as there is no access to the crankcase.
All that would not have dampened my enthusiasm. I emailed the service person at enginediy.com, as directed on the invoice should one have problems. I even told them I was waiting on a response before posting my review.
I got no response in two full HK work days, headed into the weekend now. So I’ll go ahead and report.
I could not in good conscience recommend this series of engines. Poor quality control and no reply from service has me feeling suckered. I’m done donating to them. Anybody wanna buy an inline four? They were less than helpful there also.
